I'm searching a way to put again the picture snap after the video snap, I mean when wahcade show a video snap at the end there is often a black screen, and I like to show the game's picture again (like at start)

There is an option Movies delays to start, so when If I wait 2 seconds in my choice of game I see the video, I like to have something similar to return to the picture after

Thank

EDIT: Intro movies works ?
